Tasting profile
A remarkably smooth, deep tawny with a fine, delicate intensity and exceptional balance of sweetness and fresh acidity, layered with raisins, toasted walnuts, black currant, and a whisper of orange blossom, honeysuckle, and sweet cardamom spice. The finish is bold yet subtle and extraordinarily long.

How the score was built
We compare the reviewers of this bottle against every other wine those same people reviewed. Each review is scored relative to the reviewer's own baseline — four stars from someone who hands out fives means something very different from four stars from someone who rarely goes above three. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.
